A Michican company is suing Apple claiming the technology used to measure heart rate in the latest Apple Watches infringes on its patented technology.

Why it matters: In the suit, Omni MedSci says it met with Apple from 2014 until 2016 but ultimately the company broke off discussions about a partnership, then introduced technology using its approach.

The suit, filed in the Eastern district of Texas on Friday, claims Apple willfully infringed on its patents and seeks damages and an injunction against the company.

An Apple representative was not immediately available for comment.

New Zealand weightlifter Laurel Hubbard made history on Monday as the first openly transgender female athlete to compete at the Olympics.

Why it matters: The presence of trans and nonbinary athletes at this year's Games has been celebrated by LGBTQ+ rights advocates, but stirred controversy among critics, who argue trans women have an unfair advantage even after taking hormones to lower their testosterone.
